  • Patent number: 11926017
    Abstract: A cleaning process monitoring system, comprising: a cleaning container comprising an inlet for receiving a cleaning solution and an outlet for draining a waste solution; a particle detector coupled to the outlet and configured to measure a plurality of particle parameters associated with the waste solution so as to provide a real-time monitoring of the cleaning process; a pump coupled to the cleaning container and configured to provide suction force to draw solution through the cleaning system; a controller coupled to the pump and the particle detector and configured to receive the plurality of particle parameters from the particle detector and to provide control to the cleaning system; and a host computer coupled to the controller and configured to provide at least one control parameter to the controller.
    Type: Grant

  • Patent number: 5760670
    Abstract: The present invention relates to a tranformer core structure, which includes a rectangular frame core having two long sides and two short sides, with one short side having a recessed part and the other short side being closed to form a junction surface of magnetic path; and a strip core disposed in the rectangular frame core through the recessed part, and having a length similar to that of said long side of said rectangular frame core, but having a width slightly less than that of said recessed part, wherein adjustment of the inductance of the structure is accomplished by moving said strip core along said recessed part to adjust a gap between one end of said strip core and said junction surface of magnetic path.
